A rotating disc for cutting ice in an industrial ice maker includes a center mounting hole for rotatably mounting the disc in the ice maker. The round flat top surface having a plurality of triangularly shaped through holes. The base of the triangularly shaped through holes being equally spaced from the mounting hole. The base is also positioned near the outer edge. The disc has plurality of cutter knives with triangular shapes. Each of the plurality of cutter knives are securely fastened to the round flat top surface and fixedly positioned to nearly cover each of the triangularly shaped through holes. A slot remains and extends nearly from the mounting hole to the outer edge. There is a raised portion which forms a cutting edge and is positioned over the triangularly shaped hole and parallel with the slot. The cutting edge extends nearly from the mounting hole to the outer edge of the rotating disc. A back edge of the plurality of cutter knives is flush with the round top surface and forms a sloping surface connecting each cutting edge to each back edge so that when the ice is cut, the cut part falls through the slot and the other part slides down the sloping surface to the back e…
